“All of this attention — it’s a good thing. As long as it’s not your little brother,” she says.

The ad was a stark contrast to a Lhota campaign commercial released Wednesday — which raised the specter of the city returning to its decades-old crime-filled ways if de Blasio takes the reins.

“This ad represents my belief that Bill de Blasio, and the policies he’s espoused – especially the ones he doesn’t talk about – will make this a dangerous place,” Lhota said in Far Rockaway Thursday. “I don’t think its negative at all. … I view that as my point of view.”

De Blasio slammed the ad as “fear-mongering” after an early campaign event in Manhattan.
